How much do you know about Lu Xun's satirical jokes?

Lu Xun never wrote cross talk in his life, but his dagger-throwing irony and humor are unparalleled so far. Recently, I accidentally read Lu Xun's essays and found that there are two very popular cross talk jokes, and their similar contents have appeared in Lu Xun's essays. For example, Mr. Lu Xun once told such a joke in an article: a quack peddled loudly in the market, peddling a wonderful prescription for treating bedbugs. Someone bought a paper roll, wrapped it tightly with paper, and it took a lot of effort to open it. It turns out that there are only two words on the menu: diligent grasp. Lu Xun's "magic formula" and Ma's "secret formula" of cross talk have the same effect: people will laugh when they buy "magic formula" such as "diligent grasping" and "scratching". I just don't know if this "magic formula" of Lu Xun and Mr. Ma's "secret recipe" have any inheritance relationship. For example, Su's comic dialogue "Throw Boots" was inspired by foreign humor. Perhaps it is a "coincidence" phenomenon in literary works of different times, or perhaps it has been circulated among the people for a long time.

Another joke told by Mr. Lu Xun is that when a farmer imagines how the emperor will celebrate the New Year, he can only imagine that the emperor must eat meat in a big bowl and eat rice and white flour vigorously during the New Year. This is the same as the life scene of the royal couple depicted in Liu Wenheng's cross talk "Talking about Local Opera": "The Queen of the East Palace bakes cakes and the Queen of the West Palace rolls green onions", which has the same effect. Mr. Lu Xun described the imagination of farmers in Jiangnan, while Liu Wenheng described the imagination of farmers in Shandong.
